From my 2009 vol. 2 catalog order, this is MTH's take on the new genset switchers. While it's not nearly as cool as Lionel's genset, it's still a very nice engine. I ordered a few of these in the 2-rail configuration, which comes with fixed pilots, and then I converted them for 3-rail operation. Note the scale couplers! Released in 2011, added to my set in July of 2011.
